Product Description

One of the largest uses for polyacrylamide is to flocculate solids in a liquid&period; This process applies to wastewater treatment&comma; and processes like paper making&period; Most polyacrylamide is supplied in a liquid form&period; The liquid is subcategorized as solution and emulsion polymer&period; Even though these products are often called 'polyacrylamide'&comma; many are actually copolymers of acrylamide and one or more other chemical species&comma; such as an acrylic acid or a salt thereof&period; The main consequence of this is to give the 'modified' polymer a particular ionic character&period;

Another common use of polyacrylamide and its derivatives is in subsurface applications such as Enhanced Oil Recovery&period; High viscosity aqueous solutions can be generated with low concentrations of polyacrylamide polymers&comma; and these can be injected to improve the economics of conventional waterflooding&period;

It has also been advertised as a soil conditioner called Krilium by Monsanto Company in the 1950s and today "MP"&comma; which is stated to be a "unique formulation of PAM &lpar;water-soluble polyacrylamide&rpar;"&period; It is often used for horticultural and agricultural use under trade names such as Broadleaf P4&comma; Swell-Gel and so on&period; The anionic form of cross-linked polyacrylamide is frequently used as a soil conditioner on farm land and construction sites for erosion control&comma; in order to protect the water quality of nearby rivers and streams&period; &lsqb;2&rbrack;

The polymer is also used to make Gro-Beast toys&comma; which expand when placed in water&comma; such as the Test Tube Aliens&period; Similarly&comma; the absorbent properties of one of its copolymers can be utilized as an additive in body-powder&period;

The ionic form of polyacrylamide has found an important role in the potable water treatment industry&period; Trivalent metal salts like ferric chloride and aluminium chloride are bridged by the long polymer chains of polyacrylamide&period; This results in significant enhancement of the flocculation rate&period; This allows water treatment plants to greatly improve the removal of total organic content &lpar;TOC&rpar; from raw water&period;
